The vim syntax file fortran.vim
(http://www.unb.ca/chem/ajit/syntax/fortran.vim) searches in f90 and f95
files for free fixed form comments in the first 15 lines. The regex is:
if b:test !~ '[Cc*!#]' && b:test !~ '^ \+[!#]' && b:test =~ '[^ 0-9\t]'
where b:test is the string containing a line of source code. If the line
is matched, free form is assumed.
But this method is not perfect, since the '!' might be always in the
first column for the first 15 lines, even for free form.
